Electric cars Nissan Leaf the first and second generations (ZE0, ZE1, AZE0) are equipped with a single-stage gearbox that transmits torque from the electric motor to the wheels. Despite the simplicity of the design compared to the internal combustion engine, this unit requires regular maintenance - in particular, changing the oil in the gearbox. Neglecting this procedure leads to accelerated gear wear, increased noise and even transmission breakdown.

In the official manuals Nissan often indicate that the oil is in the gearbox Leaf filled for the entire service life. However, the experience of owners and independent services shows: during intensive use (traffic jams, frequent acceleration, driving in mountainous areas), the oil loses its properties after 80–100 thousand km. In this article we will look at which oil is suitable for the gearbox. Leaf, how to check and replace it, and also answer frequently asked questions from owners.

Why does the oil in the Nissan Leaf gearbox need to be replaced?

An electric vehicle's gearbox operates in less aggressive conditions than an internal combustion engine gearbox: there are no fuel combustion products, less heating, and no synchronizer friction. However, even here the oil performs critical functions:

  • 🔧 Lubrication of bearings and gears — reduces friction and wear of metal parts.
  • 🧲 Heat dissipation — the gearbox heats up under prolonged loads (for example, when towing or driving uphill).
  • 🛡️ Corrosion protection — prevents oxidation of internal surfaces.
  • 🧹 Removing wear debris — small metal shavings settle in the oil and not on the working surfaces.

Over time the oil oxidizes, loses its viscous properties and becomes saturated with abrasive particles. This shows up:

  • 🔊 Increased noise (hum) when driving at a speed of 40–60 km/h.
  • 🔥 Overheating of the gearbox (you can feel it with your hand on the body after the trip).
  • 🛑 Jerks when starting or braking with recuperation.
⚠️ Attention: If after changing the oil in the gearbox Nissan Leaf a metallic grinding sound appears - this is a sign of critical wear of the gears. In this case, diagnostics on the lift is required: the gearbox assembly may need to be replaced.

Original gearbox oil for Nissan Leaf: part numbers and specifications

The manufacturer recommends using only original gear oil with article number KE909-99932 (for models up to 2017) or KE909-99933 (for restyled versions 2018+). This is a synthetic oil GL-4/GL-5 with viscosity 75W-85, designed specifically for highly loaded electric vehicle gearboxes.

Characteristics of the original oil:

Parameter Meaning
SAE Viscosity 75W-85
Class by API GL-4/GL-5
Pour point –40°C
Replacement volume 0.8–1.0 l (depending on generation)

The cost of original oil in official dealers Nissan - from 3,500 to 5,000 rubles per liter. Alternative options (with the same specifications):

  • 🔹 Mobil Mobilube GX 75W-85 (article 152620) - a proven analogue, used in services.
  • 🔹 Motul Gear 300 75W-85 (article 102779) - high thermal stability.
  • 🔹 Castrol Syntrans Transaxle 75W-90 (article 157F1F) - suitable for cold regions.
⚠️ Attention: Do not use oils with a viscosity 80W-90 or 75W-90 - they do not meet the requirements Nissan by fluidity at low temperatures. This can lead to increased bearing wear during cold starts.

Frequency of gearbox oil changes: when and why

Official regulations Nissan does not provide for changing the oil in the gearbox Leaf throughout the entire service life. However, experts and owners with high mileage recommend adhering to the following intervals:

  • 📅 Every 100,000 km - for moderate climates and urban use.
  • 🌡️ Every 80,000 km — when driving in hot climates (temperatures above +30°C) or mountainous areas.
  • ❄️ Every 60,000 km — for regions with frequent temperature changes (from –30°C to +25°C).
  • 🚗 Every 50,000 km — during intensive use (taxi, car sharing, frequent acceleration).

It is also worth replacing when buying used Nissan Leaf, if the mileage exceeds 80,000 km and the service history is unknown. Signs that it's time to change the oil:

  • 🔊 Extraneous noises (hum, grinding) when moving.
  • 🔥 Overheating of the gearbox housing (temperature above 70°C after the trip).
  • 🛢️ Dark oil color or metal shavings on the drain plug magnet.
💡

Even if the mileage is low, the oil is in the gearbox Nissan Leaf gets old with time. It is recommended to check its condition every 2–3 years, regardless of mileage.

Step-by-step instructions: how to change the oil in the gearbox yourself

To change the oil in the gearbox Nissan Leaf you will need:

  • 🔧 Key on 10 mm (for drain plug).
  • 🔧 Key on 24 mm (for filler plug).
  • 🛢️ Syringe for pouring oil (or funnel with a flexible tube).
  • 🧤 Gloves and rags.
  • 🔥 Container for used oil (volume of at least 1 l).

Procedure:

Warm up the car (drive 5–10 km)|Place the car on a flat surface or a lift|Put a rag under the drain hole|Prepare new oil and tools-->

  1. Drain old oil.

    Place a container under the drain plug (located at the bottom of the gearbox). Unscrew the plug with the key to 10 mm and let the oil drain (about 15-20 minutes). Pay attention to the color and presence of metal shavings.

  2. Cleaning the magnet.

    There is a magnet installed on the drain plug - it collects metal particles. Clean it carefully with a rag. If a lot of chips have accumulated on the magnet (more than 1 mm in a layer), this is a signal of increased wear of the gears - diagnostics of the gearbox is required.

  3. Filling with new oil.

    Tighten the drain plug (tightening torque - 35 Nm). Unscrew the filler plug (key on 24 mm) and using a syringe or funnel, fill in new oil to the level of the lower edge of the hole. Volume - approx. 0.8–1.0 l.

  4. Checking the level.

    Start the car, warm up the gearbox (drive 1–2 km) and check the oil level. Top up if necessary. Make sure there are no leaks around the plugs.

The entire process takes about 40–60 minutes. If you are not confident in your abilities, it is better to contact a service center - the cost of changing the oil in the gearbox Nissan Leaf at official dealers it is 1,500–2,500 rubles (excluding oil).

💡

Before adding new oil, warm it to room temperature (for example, leaving the bottle in a warm room for 2-3 hours). This will improve fluidity and make the process easier.

Common mistakes when changing oil and how to avoid them

Even experienced owners sometimes make mistakes that can lead to gearbox failure. Let's look at the most common ones:

  • 🛢️ Wrong choice of oil. Use of oils with viscosity 80W-90 or 75W-90 leads to difficulty turning gears in the cold and their accelerated wear.
  • 🔧 Re-tightening of traffic jams. Tightening torque for drain and filler plugs - 35 Nm. Exceeding this value may damage the threads or gear housing.
  • 🧲 Ignores metal shavings. If there are a lot of particles on the drain plug magnet and the oil is dark, this is a sign of wear. In this case, diagnostics are required, and not just an oil change.
  • 🌡️ Replacement without warming up. The cold oil does not drain completely, and up to 100–150 ml of waste remains in the gearbox. Warm up the car before draining!

Another common mistake is oil overflow. Excessive volume leads to increased pressure inside the gearbox, which can squeeze out the seals. The oil level should be exactly along the bottom edge of the filler hole - not higher and not lower.

What happens if you don’t change the oil in the gearbox?

Long-term use of old oil leads to:

1. Accelerated bearing wear (a hum appears at speed).

2. Bully on the gears — metal particles act as an abrasive.

3. Gearbox overheating, which may cause deformation of the housing.

4. Loss of warranty (if the car is under warranty and there are no oil change notes in the service book).

In critical cases, the gearbox assembly must be replaced (cost: from 150,000 rubles).

Differences between Nissan Leaf gearboxes of the first and second generations

Gearboxes Nissan Leaf the first (2010–2017, ZE0) and second (2018+, ZE1/AZE0) generations have design differences that affect service:

Parameter 1st generation (ZE0) 2nd generation (ZE1/AZE0)
Oil volume 0.8 l 1.0 l
Article number of the original oil KE909-99932 KE909-99933
Plug tightening torque 35 Nm 40 Nm
Filler plug location Side of the case Top (more convenient for pouring)

The second generation gearboxes have improved sealing and increased bearing life, but oil requirements remain the same. It is important not to confuse oil part numbers - KE909-99933 has an improved package of additives for protection against oxidation.

Also in Leaf 2018+ equipped with a gearbox temperature sensor. If after changing the oil an error appears on the dashboard P17F0 (transmission overheating), this may indicate:

  • Insufficient oil level.
  • Using the wrong oil.
  • Sensor malfunction (diagnostics required).

Cost of changing gearbox oil: prices in 2026

Costs for changing gearbox oil Nissan Leaf depend on the choice of oil and method of maintenance:

Service/Material Price, ₽
Original oil KE909-99932/33 (1 l) 3 500–5 000
Analogue (Mobil Mobilube GX 75W-85) 2 200–2 800
Oil change in service (work) 1 500–2 500
Drain plug gasket (if necessary) 150–300
Gearbox diagnostics (if a malfunction is suspected) 3 000–5 000

Replacing it yourself will cost 2,200–5,000 rubles (depending on the choice of oil). In the service the amount will increase to 5,000–7,500 rubles. The savings are obvious, but if you do not have experience working with transmissions, it is better to trust the professionals - mistakes during replacement can result in expensive repairs.

It is worth noting that some services offer flushing the gearbox before changing the oil (cost: RUB 1,000–1,500). This procedure is relevant if:

  • The oil is heavily contaminated (black).
  • A lot of metal shavings were found in the gearbox.
  • The car was used in difficult conditions (taxi, mountain roads).

FAQ: Frequently asked questions about gear oil in Nissan Leaf

Is it possible to use manual transmission oil instead of the original one?

Theoretically yes, but only if it meets the specifications GL-4/GL-5 and viscosity 75W-85. However, the original oil Nissan has a unique additive package optimized for operation with an electric motor. Analogues may not provide the same protection against oxidation and wear.

How to check the oil level in a gearbox without a pit?

It’s difficult to do this without a lift or pit, but you can:

  1. Jack up the rear of the vehicle (gearbox side).
  2. Remove the filler plug (key on 24 mm).
  3. The oil level should be at the bottom edge of the hole. If the oil is not visible, add more.
Important: The car must be level (no slope), otherwise the readings will be inaccurate.

What to do if a hum appears after changing the oil?

The reasons may be as follows:

  • 🛢️ Insufficient oil level (check and top up).
  • 🔧 Incorrect oil viscosity (for example, too much 80W-90 instead of 75W-85).
  • 🔊 Bearing wear (diagnostics required).
  • 🧲 Metal shavings in the gearbox (needs washing or repair).

If the hum does not disappear after adding oil, contact a service center to check the condition of the gearbox.

Is it necessary to change the oil in the gearbox if the car is under warranty?

Official dealers Nissan do not include changing the oil in the gearbox in the maintenance regulations, so failure to do this procedure will not void the warranty. However, if the gearbox fails and a lot of metal shavings are found in the oil, the dealer may refuse warranty repairs, citing non-compliance with operating conditions. We recommend keeping your oil receipts and recording the replacement in your service book..

Is it possible to mix different oils in the gearbox?

Mix oils not recommended, especially if they are from different manufacturers. Additives may react, resulting in sediment or loss of properties. If it becomes necessary to add oil, use the same brand and viscosity that was added previously. As a last resort, mixing the original oil is allowed Nissan with synthetic-based analogues (for example, Mobil or Motul), but only temporarily - perform a complete replacement as soon as possible.
